A Novel Thin Film Resistive Humidity Sensor Based on Soluble Conjugated Polymer:(propionic acid)-co-(propargyl alcohol)
摘要:
A novel soluble conjugated copolymer (propionic acid)-co-(propargyl alcohol) (PA-co-OHP) has been synthesized for the first time using a new palladium acetylide catalyst Pd(PPh3)2 (C≡CC(CH3)2OH)2 (PPB). Thin film resistive humidity sensor based on the copolymer doped with HClO4 was prepared. The impedance of the sensor changed from 103~107 W in 95%~30%RH, and the response of that is very quick (< 6 sec.). Preliminary results show the copolymer is a promising humidity sensitive material.
